' set up type wheelsto print the cashiers number, but will also control locking mechanism, so thatthe machine cannot be released for operation, unless the cashiers key is in po-- sition in the machine.

' Another object of the invention is to permit the manual release of any depressed keys which have been depressed through error, whether the cashier key is in position in the machine or not.

lVith these andincidental objects in view, the invention consists of certain novelfeatures of construction, and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form of embodiment of which is hereinafter described, with reference to the drawings which accompany and form part of this specification. v

Fig. '2 is a detailed sectional view taken on the line 22 of Fig.3.

' .Fig. 3 is a detail top plan View of the cashiers key in its proper position in the machine.

Fig. 4 is a detail view of one of the release keys of the machine, andshows the detent for locking the keys in their depressed positions,'and also the mechanism for releasing anism operated. by the cashiers key to operate the type setting racks to position a type wheel appropriate to said key.

Fig. 8 is a detail View of the ends of the racks shown in Fig. 7, and the means whereby the movement given to the racks by the cashiers key will be transmitted to its ap propriate type wheel.

Described in general terms, this invention includes a detachable cashiers key, which may be inserted in the machine or removed therefrom at will. One function of the cashiers key is to absolutely lock the machine against operation when the key has been removed therefrom. A second function is tov Release shaft This machine is provided with a shaft (Figs. '1, 4, 5 and 6) which is known herein and in the application above referred to, as the release shaft. It has been given this name due to the fact that it must be rocked in a clockwise direction, as viewed in all of these figures, before the machine can be operated. The shaft 30 normally tends to rock in a clockwise direction (Fig. 6), by reason of the following mechanism:

Fast on the shaft, is an arm 31, which at its left hand end carries a stud 32, upon which is pivotally mounted a pair of guides 33 having teats projecting into and acting as guides for a compression spring 35. At its lower end the spring 35 surroundsa teat 36, which extends upwardly from the base of a slot 37 in a link 38. It can be seen from the above that through the spring 35 and arm 31, the shaft 30' normally tends to rock in a clockwise direction.

The clockwise movement of the shaft 30 is normally prevented by means of the following mechanism:

Fast on the shaft 30 is an arm 39 (Fi ice 5), which carries a half-round stud 40, cooperating with a pawl 41, loosely mounted on a shaft 42, supported by the machine side frames.

The machine is provided with a plurality of banks of depressible keys, one of which is known as the release bank. Fig. 5 shows the uppermost key only, in this bank, and the means whereby the depression of any of the keys in this bank will release the machine. The key is slidably mounted in a frame (not shown) and has a laterally projecting pin 46, which is adapted to cooperate with an inclined edge 47, of a detent d8, supported at its upper end by an. arm 49, and at its lower end by a similar arm not shown.

The arm 49 which supports the upper end of the detent 48, has a projecting arm from which extends a pin 50. This pin normally lies just in the rear of an upwardly projecting lever 51, which is loose on the shaft 42. The lever 51 normally tends to rock clockwise, due to a spring 53 attached thereto, and thereby through its contact with the pin 50, holds the detent 48 in its normal upper position. The lever 51 carries a pin which extends through a bifurcated arm 55, which is in turn connnected to the release pawl 11 by means of a yoke 56.

It can be seen from the above description that when one of the release keys 45 is depressed, the detent 48 is moved downwardly, and thereby the arm 49 is moved clockwise about its support. This will cause the pin 50 to rock the lever 51, bifurcated arm 55, and release pawl 41, counter-clockwise a sufficient distance to move the end of the re lease pawl 41 away from the half-round stud 40, carried by arm 39 thereby permitting he spring 35 to rock the shaft 30 in a clockwise direction. The clockwise movement of the shaft 30 closes a motor switch (not snown), when a motor is provided, and causes the machine to be operated.

Cashiers key A cashiers key is provided in the present invention to positively lock the machine when the said key is removed from an appropriate slot which is provided therefor. The cashiers key is shown in Figs. 3 and 7. The means whereby the removal of the cashiers key will lock the register, will now be described.

Fast on the right hand end of the release shaft 30 is a lever 66 (Fig. 1), to which is pivoted the upper end of a. link 67. At its lower end the link 67 has a long slot 68 formed therein, which cooperates with a pin 69, carried by an arm 70, fast on a shaft 71, which is supported by a bracket 72, secured to the printer frame 73. The shaft 71 in this instance has three holes therein, in which are mounted three spring plungers or tumblers 74. The bracket 72 also has holes therein in alinement with the holes in the shaft 71, and in these holes in the bracket there are also spring plungers 75 (Figs. 2 and The bracket 72 has a key-way 76, in which the shank 77 of the cashiers key (35 is adapted to slide. Fig. 2 shows the cashiers key in position in the machine. The side of the shank 77 of the cashiers key has notches formed therein, which cooperate with the ends of the plungers 75, and which through these plungers 75 will position the tumblers 74L, so that their left hand ends (Fig. will be flush with the periphery of the shaft 71.

When the tumblers 74 are held in these positions, it is evident that the shaft 71 can be rotated, and therefore when the release shaft 30 is free to rotate clockwise by the depression of one of the release keys, this movementof the shaft 30 will be permitted. Whenever, however, the cashiers key is removed from the machine, the springs which cooperate with the tumblers 74, will force these plungers to the left, as viewed in Fig. 2, a sufficient distance to cause them to slightly enter the openings in the bracket 72, and in this manner completely lock the shaft 71 against movement. With the tumblers 7 4 in these positions, even though the release shaft 30 is free to rock clockwise by the depression of one of the keysin the release bank, this rocking movement of the shaft 30 is prevented. lVhen the cashicrs key is again inserted in the machine, the notches in the edge thereof will cooperate with the plungers 7 5, which will in turn move the tumblers 7-l: flush with the periphery of the shaft 71, so that this shaft can be rocked, and thereby permit the release shaft 30 to be rocked to release the machine.

Mean-9 for setting up fi e 10c carriers by the oasizz'ers key In order to print the cashiers number on the printing medium used in the machine, when one of the cashiers keys is inserted in the proper opening in the machine, means is provided for setting up appropriate type carriers. In order to accomplish this purpose the shank of the cashiers key carries a plurality of upwardly extending pins or wards 85, (Figs. 2, 3 and 7) which are adapted to cooperate with downwardly extending noses 86, of slidable bars 87, supported on suitable studs 88, projecting from the printer frame. These bars are normally held in their extreme right hand positions (Figs. 3 and 7) and are returned to their normal positions upon the removal of the cashiers key, by means of springs 89, which extend be tween pins on the bars, and suitable pins projecting from the'printer frame.

At their left hand ends the bars 87 have upwardly extending noses 90, which have teeth 105 cooperating with similar teeth formed in the lower edges of laterally extending racks 91, supported at their right hand ends on a stud 92 (Fig. ,7), and at their left hand endson a stud 93 (Fig. 8).

101 and 102, supported by shafts 103 and 104, projecting from the printer frame. WVhen one of the cashiers keys 65 is inserted in the keyway 76 and pushed in to its innermost posit-ion, the pins or wards 85 will come into contact with the downwardly extending noses 86 of the bars 87, and move the bars difi'erentially'toward the left, in accordance with the position of the pins on the shank of the inserted cashiers key. The movement of the bars 87 towardthe left'will through the upwardly extending noses 90 thereof, move the racks 91 also toward the left differentially, and thereby through the pinions 95, sleeves 97 or shaft 96, and partial gears 98, operate the pinions 99 and the type wheels 101 and 102 differentially to set up the cashiers number thereon;

Manual hey release Mechanism is providedfor rocking the re lease shaft 30 in a counter-clockwise direction (Figs. 1 and 4) in case the operator depresses the wrong keys in entering a transaction and wishes to return all the keys to theirnormal undepressed positions.

It will first be described how the transaction keys are locked in their depressed positions. Each of the keys 45 (Fig. 4) carries a laterally projecting pin 110, which is adapted to cooperate with a beveled nose 111, projecting upwardly from a detent 112. The detent 112 is pivotally connected at its upper end to an arm 113, which is in turn pivotally mounted on the key frame in the manner shown in the parent application previously mentioned.

The detent 112 due to the influence of a spring, not shown herein normally tends to move towards the right (Fig. 4), and thereby rock the arm113 in a counter-clockwise direction. WVhen a key is depressed a pin 110 through the nose 111 rocks the detent downwardly or towards the left (Fig. 4) until such a time as the pin passesthe lower end of the nose, whereupon thedetent will move upwardlyunder the influence of a spring as above mentioned, and the shoulder 114 of the nose 111 will engage the pm 110 and hold the key in its depressed position.

When the machine is released, an arm 115 (Fig. 4) which is secured to the release shaft 30, is rocked with the shaft in a clockwise be locked against movement.

direction. This movement of the arm 115 will position an arm 116 rigid therewith, in engagement with the upper edge of an arm 117, loosely mounted on the shaft 118. This arm 117 has a notch 119, which cooperates with a. pin 120 carried byan arm 121 rigid with the arm 113. It can, therefore, be seen that after the machine hasbeen released, it is impossible to move the detent 112, and there fore no keysin this bank can be pressed. )Vhen, however, a key 45 has been partially depressed, the arm 117 will be positioned in the path of the arm 116, and, therefore, it will be impossible to release the machine. Upon the complete depression, however, of one of the keys 45, the arm 117 again moves clockwise out of the path of the arm 116, and

the machine can thereupon be released.

In order to release the depressed keys at the end of an operation, the shaft 30 is rotated counter-clockwise, slightly past its normal position, in which it is shown in Fig. 4. This will cause the end 122 of the arm 115, to contact a beveled edge of the arm 121 of arm 113, thereby rocking the arm 113 clockwise about its pivot,vand moving the detent 112 downwardly a suflicient distance to free the pin 110 from the shoulder 114, whereupon a spring (not shown) which surrounds the shank of the key will raise thekey toits undepressed position.

Themeans for releasing the depressed keys manually will now be described. Attached to the lever 66 (Fig. 1) is a link 130, which carries a roller 131. Pivoted to the side frame of the machine is a lever 132, which has a projection 133, adapted to cooperate with the roller 131. The lever 132 is also provided with a handle 134 and when it is desired to release the keys, the lever 132 is rocked counter-clockwise. Upon this movement of the lever 132, the projection 133 thereof will contact with the roller '131 on link 130, and raise this link, which movement through the lever 66 will rock the release shaft 30 in a counterclockwise direction. This movement of the rection for the purpose of releasing the depressed keys.

When the shaft 30 is rocked counter-clockwise by the key release lever 132, to release the depressed keys, the link 67 is moved down wardly. If the cashiers key should happen to be out of the machine, the shaft 71 would For this reason a flexible connection must be provided between the link 67 and arm 7 O. The lower iii " side frame.

end of the'link 6'? has the long slot 68 formed therein, through the lower end of which the pin. 69 extends. A plunger 140 lies in the slot 68, with its lower end butting against the pin 69. The plunger is held in position in the slot by two plates 141, riveted to its sides, and extending over the sides of slot 68. At its upper end the plunger 1 ft) has a pin 142, which extends upwardly in the slot and supports a coil spring 14:3. At its upper end the spring is seated on a pin 144:, which projects downwardly from the link in the upper end of the slot 68. It can be seen from the above description that when the link 67 is lowered with the cashiens key out of the machine, the spring M3 will be compressed srdiiciently to compensate for said dowi'iward movement, and the arm 70 and shaft 71. will not be strained.

The link has a slot 14:5 cut t re/rein, through which projects a key barrel. l i-6. If it is desired to lock the machine against operation, the lever 132 is rocked so as to raise the link 130. A key is then inserted in the key barrel 146, and given a one-half rotation. A portion of the key barrel 143, which cooperates with the slot is eccentric so that upon the rotation of the key and the barrel, the link 130 will be rocked slightly counterclockwise about its pivot, and then when the handle 134 is released and the link 130 is; permitted to move downwardly, a notch 1427 on the extreme lower end of the link 1230 will engage a lug 148, which projects from the It can be seen, therefore, that so long as the link 180 rests upon the lug 148, it will be impossible to lower this link, to permit the rocking of the release shaft 30, and therefore the machine cannot be released for operation.

A shutter is attached to the lower end of the lever 32, in such a position the it normally covers the opening in the key b" 146. When the lever 132 is rocked coi clockwise, however, to its extreme position, the shutter 150 will be moved away from '11 front of the key barrel. 1%, so that the i y can be inserted to lock the machine. A spring 151 is provided, StICJCllQLl between apin on the frame and a pin on the lever 1352, to restore this lever to its normal position, when it is released by the operator.
